IMPROVEMENT IN GATES.

Specification forming part of Letters Patent No. 37,083, dated December9, 1862.

T 0 all whom it may concern.-

Be it known that I, JACOB BIOKHART, of Harlan, in the county of Allenand State of Indiana, have invented a new and Improved Gate; and I dohereby declare that the following is afnll, clear, and exact descriptionof the same, reference being had to the accompanying drawings, making apart of this specification, in which- Figure 1 is a vertical section ofmy invention, taken in the line so m,Fi 2. Fig. 2 is a plan or top viewof the same. Fig. 3 is a vertical section of the same,taken in the line111 Fig. 1.

Similar letters of reference indicate correponding parts in the severalfigures.

This invention relates to an improvement in that class of gates whichare designed to be opened by a person from a carriage or on horseback,so as to avoid the trouble and loss of time in alighting.

The object of the invention is to obtain a gate of the kind specifiedwhich may be firmly secured in a closed state and eii'ectually preventedfrom being deranged or thrown out of proper position by cattle or swine.

To enable those skilled in the art to fully un derstand and construct myinvention, I will proceed to describe it.

A represents the gate, which may be constructed in any proper manner.This gate is mounted on small wheels at, which run on a way or rail, I),placed transverselyin the road on a suitable timber,whichis embedded inthe earth so that its upper surface will be flush with the road. Therailb is of dovetail form that is to say, has inclined sides-and isfitted in corresponding recesses, a,made in the lower ends of the posts0 O of the gate, as shown clearly in Fig. 3. By this means the gate isprevented from being raised from the rail 1). The gate is retained in avertical position by having its upper bar, (1, work in a recess, 6, in abar, B, which is attached to the upper ends of posts 0 O, at oppositesides of the gate and at one side of the road. (See Figs. 2 and 3.) Therail b extends sufficiently far at one side of the road to admit of thegate A being shoved aside to leave the road entirely unobstructed, asshown in red, Fig. 2, D representing the road.

E E are two arms, which are attached at one end to opposite sides of thegate A by means of hinges ff. The opposite ends of these arms areconnected by hinges g g to bent levers F F, the fulcrum-pins h h ofwhich pass into the upper ends of the posts 0 O, as shown clearly inFig. 2. By actuating these levers F F it will be seen that the gate Amay be opened and closedthat is to say, moved across the road D, orshoved entirely to one side of it. The levers F F may be provided. withhandles i, so that they may be actuated from a considerableeminence-such as a load of hay, for instance.

The gate A is retained in a closed state by means of a sliding bar, G,which is placed directly over the bar B, and is retained in position bythe fulcrum-pins h h of the levers F, said pins passing through oblongslots 2" in the bar G, which slots admit of a certain degree oflongitudinal play or movement of the bar G. The ends of the bar G areprovided with handles 7'. The bar G, at about its cent-er,has a recess,is, made in its under side,and a recess, Z, is made in the upper edge ofthe top bar, (1, of the gate, the bar G fitting in the recess Z andpreventing the gate .A being shoved back when the recess k is not overthe recess Z. XVhen the recess 70 of the barG is over the recess Z ofthe top bar, (1, of the gate, the latter may be moved along on its wayor rail Z), for the bar G cannot in this case serve as a fastening; butwhen said bar is shoved along so that the recess k will be out of linewith the recess Z, the bar G serves as a stop, as the edges or sides ofthe recess Z will catch against the sides of said bar.

It will be seen, therefore, that in order to open the gate the bar Gmust first be moved in order to bring its recess 70 over the recess Z ofthe bar d of the gate, and the levers F F are then actuated and the gateopened or shoved to one side of the road D. In closing the gate, the barG, after the gate has reached the termination of its closing movement,is shoved so that its recess in will be out of line with the recess Z inthe bar d.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The levers F F, connected to the gate A through the medium of thearms E E, the latter being connected to the gate and the levers by meansof hinges, and all arranged as leversFF, armsEE, and gate A, allarranged shown, for the purpose of opening and eiosas and for thepurpose specified. ing the gate, as set forth.

2. The sliding bar G, provided with a recess, k, at its under side, incombination with the slot Z in the top bar, (Z,of the gate, for thepurpose of serving as a fastening for the latter, as set forth.

3. The combination of the sliding'bar G,
